GAS BURNER.

Application filed October 10, 1924, Serial No.

This invention relates to gas burners, such as used on stoves, ranges, hot plates, or the like, and an object of the 1113 611131011 is to provide in a construction of this type, a novel form of burner including a full flame burner and a simmering burner, and to assoc ate therewith a valve structure for controlling the assage of fuel to the said burners whereby t e gas ma be directed to the simmering burner or to t 1e fullflame burner as desired,

- by the operation of the single valve.

A further object of the invention is to provide a novel form of coupling which 1s utilized in connection with the simmering burner for facilitating and controlling the flow of gas or fuel thereto, operates with the novel form of valve, above specified.

Other objects of the invention w1ll appear in the following detail description, and 1n the accompanying drawings wherein:

Figure 1 is an assembled perspective view of the complete burner arrangement.

Figure 2 is a longitudinal sectional view of the simmerig burner assembly.

Figure 3 is a longitudinal section of the valve structure. I

Figure 4 is a vertical section of the valve cone.

Figure 5 is a vertical section of the elbow and sleeve. 1

,Referring more. particularly to the drawing, the full flame burner 2 has a fuel and alr supply pipe 4 of approved construction which extends out to the front edge of the stove and to which the gas or similar fuel is fed from a supply pipe through the valve structure ,6. The valve structure 6 includes the valve casing 7 having a pair of diametrically opposed laterally extending threaded nipples 8 formed thereon, one of ,which threads into the fuel supply pipe, while the other extends into the supply-pipe 4. If it is so desired, a needle valve structure 9 may be carried by the nipple 8, which extends into the supply pipe to permit regulating of the quantity of gas delivered to the burner 2. The valve cone 10 which controls the direction of flow of the gas, that is, either to the burner 2 or to the simmering burner 3, is rotatably mounted in the valve casing 7 an has a handle 11 thereon to permit its rotation. The cone 10 is provided with a relaand which co- 742,894. Renewedlcbruary 1, I929.

tively large transversely extending opening 12, which is adapted to register with the bores of the transverse nipples 8, which are formed on the valve casing 7 to permitthe fuel to flow from the fuel supply pipe to the burner 2 and also flow to the simmering burner 3 in that the cone is provided with an axially longitudinally extending opening 15 which communicates with the transverse opening 12 and opens out through the bot-tom of the Valve structure into the elbow 16 which is threaded on the valve casing; The elbow 16 has a reduced sleeve 17 formed on its lower end which projects into the pipe 18 and a needle point plug 19 is inserted in the outer end of the sleeve 17 for constricting the gas outlet opening from the elbow into the pipe 18. The pipe 18 has the simmering burner 3 threadably connected to its end remote from the elbow 16. The pipe 18has laterally opening air inlet openings 20 therein at the end of the sleeve 17, to permit aerating of the gas as it passes through the pipe 18 for delivery to the simmering burner 3.

To permit the flow of fuel to the simmering burner without permitting a flow of fuel to the burner 2, the valve cone 10 is provided with a small opening 15 which extends at right angles to the opening 12 and communicates with the opening 12, so as to permit a limited quantity of gas or fuel to pass to the simmering burner 3 without permitting gas. to flow to the burner 2.

It is, of course, to be understood, that the invention may be constructed in various other manners, and the parts associatedin different relations, and therefore, I do not desire to be limited in any manner, except as set forth in the claim hereunto appended.

What I claim is In combination, a Valve for a simmering burner and main burner including a valve casing with a transverse passage, a cone mounted in said casing and provided with a transverse relativelyi large opening to cooperate with closely adj oining parts of the passage, whereby a main supply of fluid may he conducted to the main burner, said cone having a vertical passage extending upwardly from the smaller end of the cone and merging into said opening and communicating with the simmering burner, whereby fluid may flow to the simmering burner simultaneously with 5 the first named opening,

the flow of fluid to the main burner, said cone having asecond relatively small horizontal opening formed in the side wall of the cone to one side of and at right angles to and adapted to register with the entrance portion of said transverse passage, when the first named opening is out of register with and at right angles to the transverse passage, whereby the fluid to the main burner is shut off and fluid admitted to the simmering burner-independently.

In testimony whereof I aflix my signature.

MAX KRAVITZ.
